I used my ability to view stereoscopic pictures by crossing my eyes and found no evident difference. Nice try.
I do this, too!
Was a fad around 1990. You could use it as a party gag impressing people with solving "find the differences" riddles lightning fast. Just hold your pencil over the side that your dominant eye chooses then cross out what scintillates :) Jaws will drop
Duplication is intentional. I just thought it was a cool idea. iMac boxes configured into a wheel.
It is! 😊
